Original Commit Message:

    Code object iteration was missing logic for RELATIVE_CODE_TARGET
    reloc entries. Garbage collection could thus miss objects that were
    referenced only as targets of pc-relative calls or jumps.

    RELATIVE_CODE_TARGETs are only used on arm, mips, and s390 and only
    at mksnapshot-time.

    This exposed another issue in that the interpreter entry trampoline
    copy we generate for profiling *did* contain relative calls in
    runtime-accessible code. This is a problem, since code space on arm is,
    by default, too large to be fully addressable through pc-relative
    calls. This CL thus also disables the related
    FLAG_interpreted_frames_native_stack feature on arm.

    objects.
